- type
1-character string giving the type of plot desired. The
following values are possible, for details, see plot:
"p" for points,
"l" for lines,
"b" for both points and lines,
"c" for empty points joined by lines,
"o" for overplotted points and lines,
"s" and "S" for stair steps and
"h" for histogram-like vertical lines. Finally,
"n" does not produce any points or lines.
- dodge
Adjustment parameter for dodging overlapping points or ranges in
grouped plots along the x-axis (or y-axis for flipped plots). Either:
numeric value in the range [0,1). Note that values are scaled
relative to the spacing of x-axis breaks, e.g. dodge = 0.1 places the
outermost groups one-tenth of the way to adjacent breaks, dodge = 0.5
places them midway between breaks, etc. Values < 0.5 are recommended.
logical. If TRUE, the dodge width is calculated automatically based on
the number of groups (0.1 per group for 2-4 groups, 0.45 for 5+ groups). If
FALSE or 0, no dodging is performed.
Default value is 0 (no dodging). While we do not check, it is strongly
recommended that dodging only be used in cases where the x-axis comprises a
limited number of discrete breaks.
- fixed.dodge
Logical. If FALSE (default), dodge positions are
calculated independently for each x value, based only on the groups
present at that position. If TRUE, dodge positions are based on all
groups, ensuring "fixed" spacing across x-axis breaks (i.e., even if some
groups are missing for a particular x value).
